Q160

What will be the result of following function call in LISP? >(/ 7.0 2)

A) 9.0
B) 3.5
C) 7/2
D) 7.02

Q161

In Ada, tagged type definition is performed in a _______.

A) Record
B) Template
C) Structure
D) Package

AI Explanation

In Ada, tagged types are defined as tagged records. They extend record types to support object-oriented features such as inheritance and polymorphism.

Q162

___________ is the Equality Operator in ADA.

A) =:
B) :=
C) ==
D) =

Q163

The correct way to declare an 'access' type in Ada is:

A) type ref_type:= Address;
B) type ref_type = Address;
C) type ref_type is access Address;
D) type ref_type :: Address;

AI Explanation

Ada declares access types using the 'is access' syntax. Access types provide pointer-like capabilities for referencing dynamically allocated objects.

Q164

To terminate a simple loop in Ada, which of the following statement is used?

A) break
B) end
C) exit
D) finish

AI Explanation

In Ada, the exit statement is used to terminate a simple loop before its normal completion. It transfers control out of the loop.

Q165

Consider the following two statements written in Ada: type Months is (January, February, March, April, May, June, July); type Monthly_Sales is array(Months) of Float; What is size of array named ‘Monthly_Sales’?

A) 7
B) 8
C) 2
D) 3

AI Explanation

The enumeration type Months contains seven values from January to July. Therefore, the array Monthly_Sales has seven elements, one for each month value.

Q166

Which of the following statement of LISP creates an array of size 5?

A) (make linear-array (5))
B) (setf (make-array ‘(5)))
C) (setf linear-array (make-array ‘(5)))
D) (setq linear-array (array ‘(5)))

AI Explanation

In LISP, make-array is used to create arrays, and setf assigns the created array to a variable. This statement correctly creates an array of size 5 and stores it in linear-array.

Q167

Disjunction in Prolog is through ________and conjunction is through _____.

A) OR, Dot(.)
B) Coma (,), OR
C) OR, coma (,)
D) Dot(.) , OR

AI Explanation

In Prolog, disjunction is represented using OR (written as ; in actual Prolog syntax), while conjunction is represented using a comma. These operators combine alternative and simultaneous goals respectively.

Q168

Each axiom in PROLOG program is:

A) an object
B) a function
C) Conditional statement
D) Horn clause

AI Explanation

Axioms in Prolog are represented as Horn clauses, which form the basis of logic programming. They describe facts and rules used by the Prolog inference engine.

Q169

LISP was the first programming language that introduced the concept of ________.

A) Pointers
B) Dynamic typing
C) Trees
D) Arrays

AI Explanation

LISP was one of the first programming languages to introduce dynamic typing, where variable types are determined at runtime. This provides flexibility in handling different kinds of data.

Q170

Expert system___________ provide a structure to design expert system.

A) Techniques
B) Shells
C) Mechanism
D) Lists

AI Explanation

Expert system shells provide a framework or structure for designing and developing expert systems. They include tools such as inference engines and knowledge representation mechanisms.

Q171

A PROLOG program can have:

A) Multiple Goals
B) Even number of goals
C) Odd number of goals
D) Exactly one instance of a goal

AI Explanation

A PROLOG program can contain multiple goals that can be queried and evaluated by the inference engine. Each goal represents a condition or problem to be solved.

Q172

The correct way to write Goal for following statement in PROLOG is _________________. "Which medicine relieves in diarrhea?"

A) M (relieves, diarrhea).
B) M (diarrhea, relieves).
C) diarrhea (relieves, M).
D) relieves (M, diarrhea).

AI Explanation

In PROLOG, the predicate should represent the relationship being queried. The statement asks which medicine relieves diarrhea, so the predicate 'relieves' with arguments medicine and condition is appropriate.

Q173

The first programming language to support Recursion was ________.

A) FORTRAN
B) LISP
C) ADA
D) COBOL

AI Explanation

LISP was the first programming language to support recursion as a fundamental feature. Recursion became a central technique in symbolic processing and artificial intelligence applications.

Q174

Following statement in PROLOG is considered as ______________________. "unsuitable_for(Person, Drug) :- aggravates(Drug, Condition), suffers_from(Person, Condition)."

A) Goal
B) Variable
C) Rule
D) Fact

AI Explanation

The given PROLOG statement has a condition followed by a conclusion using the ':-' operator, which defines a rule. Rules describe relationships that are true when their conditions are satisfied.

Q175

Problem solving in PROLOG is achieved by using:

A) Streams
B) Facts
C) Functions
D) Objects

AI Explanation

In PROLOG, problem solving is achieved by defining facts and rules that represent knowledge about a problem domain. The inference engine uses these facts to derive solutions.

Q176

In Prolog, we specify _______and do not specify _________.

A) Result , Inputs
B) Facts, Problem
C) Result , Outputs
D) Problem , Solution

AI Explanation

In Prolog, programmers specify the problem in terms of facts and rules, while the system determines the solution through logical inference. This differs from procedural languages where algorithms are explicitly defined.

Q177

A list in PROLOG can have elements of ________ type and size.

A) Three
B) Fixed
C) Arbitrary
D) Two

AI Explanation

A list in PROLOG can contain elements of arbitrary type and size. This flexibility allows lists to store different kinds of data and grow dynamically.

The main feature of PROLOG language is its ability to handle and process __________.

A) Objects
B) Classes
C) Functions
D) Symbols

AI Explanation

PROLOG is designed for symbolic processing and logic programming, making it effective at handling and processing symbols. It is widely used in artificial intelligence applications.

Q179

The basic tool for writing programs in PROLOG is:

A) Polymorphism
B) Recursion
C) Object-Orientation
D) Inheritance

AI Explanation

Recursion is a fundamental tool for writing PROLOG programs because many problems, especially list processing tasks, are naturally expressed recursively. PROLOG relies heavily on recursive definitions and queries.
